UNITED STATES WILLIAM K.. ROCKMAN, OF NEW YORK, N. Y.

FOUNTAIN BRUSH.

Application filed May 23, 1923.

To all whom. it may concern;

Be it known that I, IVILLIAM K. ROOK- MAN, a citizen of the Chinese Republic, residing in New York city, in the State of New York, have invented certain new and useful Improvements in Fountain Brushes, of which the following is a specification.

My invention relates to a fountain brush which is especially adapted for use by a writer of the Chinese language.

The object of my invention is to provide a fountain brush in which the ink is efficiently and automatically supplied to the bristles.

Another object of my invention is the provision in such a fountain brush of means for holding the bristles in effective working position.

Still another object of the invention is the provision in such a fountain brush of means for feeding air during the use thereof through which the ink does not enter or leak when the pen is being refilled or when the device is not in operative position.

With these and other objects in view which will be apparent as the description proceeds I "provide a device such as is shown in the accompanying drawings, in which:

Figure 1 is a perspective view of the device with the cover for the brush in place;

Figure 2 is a perspective view of the device, the cover being shown in section; and

Figure 3 is a sectional view through the device without the cover.

In the drawings, 1 indicates the handle of the pen, which is hollowed out to constitute the ink container; 2 indicates the air feed tube which is inserted at its upper end and fastened into a plug 3, which latter is provided with an air pipe 4 continuous with the tube and at right angles thereto. Into the lower end of the air feed tube is inserted a holder 5 which carries the feed wire 6, the holder 5 being provided with a passage way for the air from the tube. The plug 3 is secured, as by screw threads, into the upper extremity of the handle 1.

The. lower extremity of the handle 1 is provided with a plug 7 having a hollow tapered opening 8 therethrough, terminating in a narrow passageway through which Serial No. 640,917.

passes the feed wire 6. The tapered opening and passageway have a metal tube 9 fastened therein, this tube extending beyond the plug 7 and forming a protector and prolonged ink feeding tube for the feed wire. The plug 7 is screwed into the handle 1 so that it may be removed in order to fill the ink reservoir. In this connection, attention is directed to the fact that the arrangement shown effectively prevents ink being drawn into the air feed tube during the filling since the air exit passage or passages in the holder 5 are at the extremity of the feed tube.

Surrounding the lower periphery of the plug 7 is the protecting sleeve and holder 10 for the bristles 11; this sleeve is secured to the plug 7 in any suitable manner and preferably abuts against a shoulder on the plug as shown.

The handle and the plugs 3 and .7 are made of hard rubber or similar material, such as the phenol condensation product known as bakelite, while the tube 9 and the feed wire 6 are preferably made of brass and the bristles protecting sleeve 10 of gold or silver. I do not desire to limit myself to any particular materials in the manufacture of my fountain brush, since it is obvious that many materials might be used to advantage.

The operation and function of the bruslr will be apparent from the above descrip-- tion, and it is therefore only necessary to set forth briefly the cooperation of the various parts. The partial vacuum which exists in the ink reservoir, owing to the fact that it is not completely filled at any time, will prevent the ink from dropping off of the bristles when not in use, while the air entering the air feed pipe will proceed along the same and supply the necessary amount to feed the ink when the brush is in use, the ink following the feed wire ensuring a constant and even flow of ink to the bristles.

A cover 12 for the bristles is provided which is formed with screw threads cooperating with threads on the handle 1- so that the bristles may be protected when not in use. The cover is provided with a metal carrying clip 13 of the usual form, the clip extending through the cover 12 and being fastened in position by means of a ring 14.

Having thus described my invention, what reservoir, an air feed tube -extendinglongrtudinally thereof, a feed wire mounted in the tube adjacent the exit end ofthe'ink' reservoir and bristles surrounding the feed wire.

2. In a device ofthe class described, a hollow-handle member constituting an ink reservoir, a feed wire located adjacent the exit end of the ink reservoir, bristles surrounding the feed Wire and means whereby air is fed to the feed Wire simultaneously with the ink.

3. In a device of the class described, a hollow handle member constituting an ink reservoir, an -air feed tube, a feed wire, bristles surrounding the feed wire, a holder 'forthe fee-d wire located in proximity to the exit end of the air feed tube, an air passage way in the holder, the ink reservoir exit and the air passage way exit being adjacent each other and in the same plane.

In testimony whereof I'aflix my signature.
